Too bouncy
August 12, 2020
Even though this mattress is dual sided but we still find it too bouncy for our baby. Whenever he moved, the mattress would bounce too much. We have a different mattress for our toddler and it was much better. You get what you pay for! If we could do it again, I would spend a bit more and buy a different mattress.
  • Cheap
  • Poor support and stability

Solid purchase
August 1, 2020
I got a fantastic deal on this mattress and am happy with my purchase! Love the dual sides for infant/toddler. The infant side is truly firm, unlike many I felt in stores. I feel comfortable with my baby sleeping on it, and he won’t sink down into it like a softer mattress would do. The color is lighter than in the picture. It is a tad noisy, but with a mattress pad and sheet it should be fine. The waterproof shell is worth the bit of noise, in my opinion. Shipping was great, as always, and it came well packaged.

The mattress comes in flat shape without any rolling, that's really good! And no smell and the waterproof cover looks good too.

Great Mattress & great price
July 15, 2020
I got this mattress on sale because it is almost identical to my older kid's mattress. It arrived super fast and has been wonderful! It was a little too hard for my baby, but as soon as I added a mattress protector under the sheet he loved it!

It’s a mattress
May 22, 2020
This mattress will definitely last a while, it looks to have good construction, quiet, has dual sides for infant/toddler sleep, and it fits perfectly in the crib. The downside is that if the tags came off for whatever reason it would be difficult to tell which side is which and the mattress is very stiff so if you have a sheet without much stretch it is a bit hard to get on. Overall I would buy it again.
  • Dual sides
  • Quiet
  • No gap between crib and mattress
  • Hard to get a sheet without stretch on

Just ordered the mattress for our son showing up in June. I can’t say enough good about Albeebaby, all of the orders we have placed seem to show up at 3-4 days after order and in great shape. As far as first looks the mattress in the box, it looks great.. no complaints here..
  • Easy order, easy delivery, quick service, can’t say enough good...

Almost overly pleased
April 17, 2020
I was holding off on buying a new crib for awhile because of costs and nursery space. I was using a Graco Pack n Play XL for the first couple of months of my child's life but he quickly outgrew the bassinet. Being a fairly tall person made bending down to the floor to pick up my 18 lb child tiresome so I went ahead and bought a West Elm crib. Mattresses for infants are full of ridiculous claims that they will change your life and you wont ever worry about a good nights rest yada yada.

This mattress might actually do just that. My kid was co-sleeping for the past month and he was constantly tossing and turning. The first nap on this mattress lasted 30 minutes longer than in his pack n play. The first night had fewer wakeups. As always, thankful for the pricing and the wide selection.
  • Labeled infant side
  • Mattress is already protected
  • Easy wipe down
  • Slightly squeaks when baby moves

Sneaky mattress
April 10, 2020
I bought this mattress because price was decent, has good reviews and is a dual mattress. Which is great because when she becomes a toddler I can just flip mattress over. My daughter seems to like the mattress. She sleeps pretty good. My only complaint is when I lay her down ,it’s loud (since mattress has waterproof surface) other than I like it.
  • Affordable & doesn?t have a plastic smell
  • Mattress is a bit noisy

great mattress and deal
February 12, 2020
I order this mattress after months of research I order 2 for my twin grandsons, the reach did not let me down unlike some of the reviews it did not come torn or ripped. Also the customer service was great. Unfortunately I received only one mattress which arrived in 3 days from order. When I called they were nothing but polite apologized for the error and I received the other one in two days. The mattress was nice and frim on the infant side and was also conformable on the toddler side. They also fit perfect in the cribs, no spacing on any of the sides. I was also pleased with the Albeebaby price. All other vendors were much more and there were shipping fees even if shipped to stores. It was great having it shipped to my home for free!!! The price was like buying one getting one free!!!. The true test will be when the boys come home. I also order 2 more for a nursery in my home, they have not arrived yet but are on the way, again in three days from order.
  • price, quality, free shipping, good customer service.
  • none as of yet

Ordered for baby on the way. It fits in the crib tightly. The tag makes it easy to determine which side is for infant and toddler. It seems like a really sturdy mattress.

It looks like a great mattress. We haven't had a chance for our daughter to use it since shes not born yet but it doesn't have any chemical smell even though its got a plastic cover. I cant tell the difference in the softness between the toddler and the infant sides but the tag clearly states which side is which.

This far we really like this mattress. It has firm sides which was important feature for me as our old crib mattress gave in too much. No plasticky odor either. I would say this is a solid choice for a newborn/baby/toddler mattress.
